Raws li lub zog ntawm cov khoom muaj peev xwm kom tau txais cov khoom siv hluav taws xob, nws tuaj yeem muab faib ua oxidants muaj zog, nruab nrab oxidants, thiab tsis muaj zog oxidants los piav qhia txog nws qhov kev ua tau zoo hauv cov tshuaj tiv thaiv redox. Txawm li cas los xij, ciam teb ntawm qhov kev faib tawm no tsis meej. Qee zaum, ciam teb yog raws li cov pa oxygen (O2 / H2O, E∅=1.229V [2]) thiab hlau ions (Fe3+/Fe2+, E∅=0.771V [2]). Cov tsiaj uas muaj zog oxidizing ntau dua cov pa oxygen yog cov oxidants muaj zog, cov uas tsis muaj zog tshaj cov hlau ions yog cov oxidants tsis muaj zog, thiab cov nyob nruab nrab yog cov oxidants nruab nrab. Raws li lawv qhov kev txaus ntshai, lawv tau muab faib ua thawj oxidants thiab lwm yam oxidants.
Oxidants tau muab faib ua cov oxidants tsis muaj zog thiab cov organic oxidants raws li lawv cov tshuaj muaj pes tsawg leeg. Lawv tuaj yeem muab faib ua peb pawg hauv qab no raws li qhov nruab nrab xav tau rau cov tshuaj tiv thaiv oxidation:
(1) acidic nruab nrab oxidants (piv txwv li, hydrogen peroxide, peracetic acid, sodium dichromate, chromic acid, nitric acid, poov tshuaj permanganate, ammonium persulfate).
(2) Cov tshuaj oxidizing nyob rau hauv alkaline media (piv txwv li, sodium hypochlorite, sodium percarbonate, sodium perborate, poov tshuaj perborate).
(3) Oxidizing cov neeg ua haujlwm hauv cov xov xwm nruab nrab (xws li bromine, iodine).
